I really enjoy the FG - it's got all the chrome-and-leather soul you want from an older SLR, shutter is very accurate, it "just works".
Except when it doesn't - sometimes the advance mechanism gets jammed, a common enough problem to have a youtube video. You have to open the bottom and fiddle with where the framitz actuates the gonadical truss gear. Or something.
Also, if, when you pick up any of your old cameras to check the batteries before loading film... well, the FG doesn't turn on until you load and advance the film. I've forgotten that enough times to really waste some batteries.
If you can live with plastic and AF, I really think the deal-of-the-century is an N90s with the battery grip. They go for next to nothing, they use plain old AA batteries, have a fast motor drive and all the pre-digital exposure bells and whistles. Chances are the rubberized coating on the back is now sticky, so you have to pop off the back and clean with goo-gone, alcohol or what have you. Only missing feature is multi-exposure (which requires the data back). Erg9onomically, it's a great setup with the grip, and reasonably small. If you want multi exposure, the 8008 or 8008s is a good "modern" choice, and again, dirt cheap. Another plastic camera though and Nikon never made a grip for it.
